FAQs about being a Java Developer
What is the difference between JDK, JRE, and JVM?
JDK stands for Java Development Kit, which provides tools for developing Java applications. JRE is the Java Runtime Environment, which provides libraries and other components to run Java applications. JVM, or Java Virtual Machine, is the engine that executes Java bytecode.
How does Java achieve platform independence?
Java achieves platform independence through the use of the Java Virtual Machine (JVM). Java code is compiled into bytecode, which can be executed on any system that has a compatible JVM, regardless of the underlying hardware or operating system.
What are the main principles of Object-Oriented Programming in Java?
The main principles of Object-Oriented Programming (OOP) in Java are encapsulation, inheritance, polymorphism, and abstraction. These principles help in organizing code, promoting reusability, and improving maintainability.
